This most frequently includes downloading the WordPress package from WordPress.org, uploading it to the web server through FTP, and running the installation script by pointing your web browser to your domain.

WordPress definition of a child theme: A child theme inherits the properties and functionality of its parent on WordPress. It does not independently function from a parent theme. The child theme can be used by developers for further modifications without disturbing the code of the parent theme.  

There are two ways you can customize. One via CSS, and the other via PHP. If CSS, this can include:

• Making a new folder in the themes directory and naming it the same as the parent, but with other added names like child.
• Making a style sheet.
• Enqueue parent and child theme stylesheets, making sure to have the child theme load before the parent.
